Resumo


Os corantes azoicos constituem a classe de corante mais usada industrialmente, constituindo alguns dos principais contaminantes de efluentes industriais. O corante Ponceau 4R (Acid Red 18) é um corante azoico utilizado em diversas indústrias têxteis e alimentícias e deve ser eficientemente removido de águas residuais industriais. Neste estudo, avaliou-se a utilização de sílica gel comercial modificada superficialmente com 3-aminopropiltrietoxisilano (APTES) na remoção do corante Ponceau 4R. Preliminarmente, foram realizadas a funcionalização da sílica gel com APTES e a otimização do pH dos ensaios adsortivos. Então, dados de cinética e de equilíbrio de adsorção foram determinados, em temperatura de 30 ◦C, pH 3,0 e agitação de 160 rpm. Modelos cinéticos de pseudo-primeira ordem e pseudo-segunda ordem, e isotermas de equilíbrio de Langmuir e de Freundlich, também foram ajustados aos dados determinados. Capacidades de remoção do azo-composto superiores a 47 mg/g foram obtidos com velocidades de adsorção relativamente elevadas, indicando que o adsorvente avaliado é bastante promissor na remoção do corante azoico estudado. Mencione-se, ainda, que o modelo de pseudo-segunda ordem se ajustou bem aos dados cinéticos, enquanto que ambas as isotermas de Langmuir e Freundlich se mostraram insatisfatórias na representação dos dados de equilíbrio determinados.
